| Application: | Sodium sulfate can be used as a dehydrating agent for the synthesis of 1,3-diaryl-2-propen-1-one oxime via the condensation of 1,3-diaryl-2-propen-1-one with hydroxylamine hydrochloride. It can also be used as a drying agent in organic synthesis for the removal of traces of water from organic extracts. It is used for drying almost all compounds including fatty acids, aldehydes, ketones, and alkyl and aryl halogenides. |
| Features and Benefits: | • Increased efficiency – Eliminates time and effort of loosening hardened powders • Safety – Eliminates tools of force used to break up clumps • Ecology – Reduces waste as it does not stick to the packaging • Economy – Faster preparation and solvation increase productivity and reduce costs • Assured quality – Excellent, expert-tested quality with no anti-caking agents • Flexible volumes – Available from research amounts to scale-up quantities |
